This test is crashing because `ENABLE_IOS_TOUCH_EVENTS==0` in open source iOS EWS and we don't know how to handle `_WKWebsiteMouseEventPolicySynthesizeTouchEvents` in this configuration.
```
static WebCore::MouseEventPolicy coreMouseEventPolicy(_WKWebsiteMouseEventPolicy policy)
{
    switch (policy) {
    case _WKWebsiteMouseEventPolicyDefault:
        return WebCore::MouseEventPolicy::Default;
#if ENABLE(IOS_TOUCH_EVENTS)
    case _WKWebsiteMouseEventPolicySynthesizeTouchEvents:
        return WebCore::MouseEventPolicy::SynthesizeTouchEvents;
#endif
    }
    ASSERT_NOT_REACHED();
    return WebCore::MouseEventPolicy::Default;
}
```
